If you were wondering why my blogging has dropped off in recent months, wonder no more. I’ve been fully immersed in the next release of VSAN. Today VMware has just announced the launch of VSAN 6.2, the next version of VMware’s Virtual SAN product. It is almost 2.5 years since we launched the VSAN beta at VMworld 2013, and almost 2 years to the day since we officially GA’ed our first release of VSAN way back in March 2014. A lot has happened since then, with 3 distinct releases in that 2 year period (6.0, 6.1 and now 6.2). For me the product has matured significantly in that 2 year period, with 3,000 customers and lots of added features. VSAN 6.2 is the most significant release we have had since the initial launch.

Alright, my normal RAID-5 caveats stand here. Pretty much every RAID level other than 0 is better than a single parity RAID, until RAID goes away. If you care about your data and speed, go with RAID-10. If you’re cheap, go with RAID-6. If you’re cheap and you’re on antique hardware, or if you just like arguing about bits, keep reading about RAID-5.
